In this example of execution, top cover 1 is connected to one side of bottom case 2 through hinge 4. Therein, as in showed in Figure 2 to Figure 6, the end of hinge 4 is connected to the edge on outer side of bottom case 2, and a turn-over slot 204 is set up in the position on top of the edge of bottom case 2 corresponding to hinge 4, the other end of hinge 4 is connected to the inner side of top cover 1, so it realizes the connection of top cover 1 and bottom case 2; in this example of execution, a turn-over slot 204 is set up in bottom case 2, so it realizes the turn over of specified angle (such as 270°) of the connecting point of top cover land bottom case 2.
In a replaceable way, hinge 4 can be replaced with hinge module. Please refer to Figure 17 for the structural schematic diagram of an available type of hinge module. Hinge module 5 contains one hinge 51 of pivotal connection and one top cover hinge 52, therein, the hinge 51 contains the first connection sheet 511 and the first connection end 512, such hinge 51 is connected to bottom case 2 through the first connection sheet 511 in a fixed way; the top cover hinge 52 contains the second connection sheet 521 and the second connection end 522, such top cover hinge 52 is connected to the inner side of top cover 1 through the second connection sheet 521 in a fixed way; in addition, the first connection end 512 of hinge 51 is connected to the second connection end 522 of top cover hinge 52 through a pivotal connection end 53 in a pivotal way.

The conduit 73 can be used to protect the wire. The length of conduit is slightly longer than joint pipe 411 for the convenience of entrance of wire during installation and use. End cap 75 is set up in one end of the joint pipe 73, end cap 75 is connected with the screw thread of joint pipe 411, and one end of the conduit 73 passes through the wiring hole of end cap 75. The material of the end cap can be rubber and rubber end cap can protect the wire.
During application, joint pipe 411 is connected with engaging lug 722 through the bolt in a rotational way, gear pressing plate 71 is connected with joint pipe 411 through bolt 74 and the gear slot matches the gear teeth of gear 721. In case of any adjustment of the angle, screw 74 shall be loosened to separate the gear slot 711 of gear pressing plate 71 and the gear teeth of the gear 721, to adjust the joint pipe 411 and the connecting piece 72 to a suitable angle, and then tighten screw 74 to match the gear slot 711 of gear pressing plate 71 and the gear teeth of the gear 721, and it can fix the relative position of joint pipe 411 and the connecting piece 72, so joint pipe 411 and connecting piece cannot rotate around the bolt, and the adjustment of angle is completed.
Most of the weight of the lamp holder in this example of execution is distributed to the screw connecting the gear pressing plate and the joint pipe, in the meantime, the shaft connecting the joint pipe and the engaging lug also bears the radial force, so the connection of the joint pipe and the connecting piece is more solid and the connection strength is improved. In addition, the switching equipment in this example of execution applies the meshing of gear pressing plate and the gear, and the range of adjustable angle is large and the two pieces are not easy to dislocate or fall off.
Through the setting up of angle-adjustable connecting member, the straight-arm-type LED lighting device in this example of execution can also have the function of adjusting the angle of installation of the lamp.
